LIGHT EMITTING DEVICE, DISPLAY DEVICE USING IT, METHOD OF DRIVING LIGHT EMITTING DEVICE, AND METHOD OF DRIVING DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light emitting device capable of extending the service life of an electron releasing part and preventing a non-uniformity phenomenon of brightness by using an anode current to judge deterioration of the electron releasing part so as to compensate the anode current reduced due to the deterioration, and to provide a display device, a method of driving the light emitting device, and a method of driving the display device. SOLUTION: The light emitting device includes: a plurality of gate lines; a plurality of data lines; a panel assembly including a plurality of pixels defined by the plurality of the gate lines and the plurality of the data lines; a plurality of scanning lines; a plurality of column lines; a plurality of emitting pixels defined by the plurality of the scanning lines and the plurality of the column lines; and an anode electrode. The light emitting device transmits a scanning signal to the emitting pixel in a first scanning on voltage and a first scanning on period; and compensates an anode current by increasing at least one of the first scanning on voltage and the first scanning on period when the anode current decreases by non-uniformity of brightness of the plurality of the emitting pixels by detecting the anode current.
